1. A hand-held instrument, comprising:a handle portion;
an electrosurgical electrode supportably interconnected to and extending distally away from a first end of said handle portion in a first direction;
a signal cable, extending proximally from a proximal end of the handle portion to an interconnected coupler end that is provided to interface with an electrosurgical generator, for transmission of electrosurgical signals to the electrosurgical electrode via the signal cable;
at least one electrically-powered light source, interconnected to said handle portion, for emitting light in said first direction to illuminate a volume extending along the electrosurgical electrode from said first end of the handle portion to a distal end of the electrosurgical electrode;
at least one battery, disposed remotely from said handle portion, to provide electrical power to said at least one light source as a DC signal;
an electrical cable, extending proximally from the proximal end of the handle portion to an interconnected battery module for supporting said at least one battery, to provide said electrical power from said at least one battery to said at least one light source via the electrical cable; and
a switch, interconnected to said handle portion and in electrical communication with said at least one battery by said electrical cable, for selective activation of said at least one light source by said electrical power form said at least, one battery.
